Product Description:

Bosch Rexroth Indramat manufactures the MDD090A-N-030-N2L-110GL1 synchronous servo motor, a member of the MDD Synchronous Motors series. The unit is built for digital drive controllers that demand rapid response and stable speed regulation. By translating controlled stator currents into torque, it moves mechanical loads in packaging lines, transfer systems, and general factory automation where compact framed motors with standardized dimensions simplify integration. Its servo-oriented design also supports axes that must start, stop, and reverse with consistent motion behavior.

In operation, the motor can deliver a continuous standstill torque of 3.7 Nm, which is the steady load it can hold without overheating when the rotor is locked. During acceleration or emergency stopping, the integrated blocking brake applies up to 6.5 Nm of static torque to restrain the shaft mechanically. Nominal speed is rated at 3000 rpm, so the rotor can run at a speed suited to direct coupling with gear stages used in medium-speed processes. Mechanical centering during installation is aided by a flange pilot diameter of 110 mm, which helps maintain concentric alignment with gearboxes or mounting surfaces. All power and feedback lines exit on the left side, helping organize cable routing in compact multi-axis machines.

The motor uses a molded housing with standard mass balance to keep vibration within ISO G 6.3. Electrical terminations use a single connector, which keeps the motor-side connection layout simple. Rotational data returns through digital servo feedback to maintain closed-loop accuracy over the full speed range. The hardened steel shaft is a plain shaft with no keyway, minimizing runout when clamped by taper collars, and a positively fitted shaft seal guards the bearing set against coolant splash and airborne debris.
